What is the standard for safety capacitors?

A capacitor, usually referred to simply as a capacitor, is a capacitor. In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a component that can store electric charge and is one of the commonly used electronic components. The role of the capacitor: coupling, filtering, decoupling, high frequency vibration, resonance, bypass, neutralization, timing, compensation, frequency division, load capacitance and so on. What are the criteria for detecting safety capacitors in daily use?

The standard for checking the safety of a safety capacitor can be touched by hand, and there is a problem in appearance. Do not use long or short legs. It can also be tested with a multimeter. The detection of the safety capacitor needs to connect the multimeter red pen to the negative pole and the black test lead to the positive pole. At the moment of contact, the multimeter pointer is deflected to the right by a large degree of skewness. For the same electrical block, the larger the capacity, the larger the swing, and then gradually turn to the left until it stops at a certain position. The resistance at this time is the forward leakage resistance of the electrolytic capacitor, which is slightly larger than the reverse leakage resistance.

Practical experience shows that the leakage resistance of a capacitor should generally be several hundred kΩ or more, otherwise it will not work properly. In the test, if there is no charging in the forward and reverse directions, that is, the hands are not moving, the capacity disappears or the internal circuit is broken; if the measured resistance is small or zero, the leakage of the capacitor is large or the breakdown is broken. Can no longer be used.

In the procurement of safety capacitors, we must choose a regular manufacturer, and the quality is guaranteed. A capacitor that does not affect the human body even if it fails. Due to its high security performance, it has become a popular product in capacitor products and is highly favored.
